Hi prabhu,

I think for u r requirement..

create viewcontroller under the tab.

in code menction like below.

If   SELECTED_TAB   =  'Request'.

then  create instance and call component...

endif.

No code is required Prabhu,

just inser a ViewContainer UI element on specific TAB, then go to window, try to embed view, then automatically the view/window which is from another component will display, just select that.

now, whenever you click on that TAB, view/window of second component will be displayed.

Hi Venkat & Chengalarayulu D,

Now the respective view is populating in respective tab.But the value is not populating in the respective view.

It should populate while clicking the onaction itself.

can u tell where i have to write the code in the onaction of the button else?

Explain in step by step process.Wheather u have any sample code please send me..

[chengalarayulu · Accepted solution]

then, you just create an action for TABSTRIP, onSelect action you can compare like Venkat said above,

if SELECTED_TAB = 'TAB1'.

     *** do

elseif SELECTED_TAB = 'TAB2'.

     *** do

endif.

Hi

In the onaction of display button we can't write the code.Because tab is using 2nd component.we can't get the selected tab in the 1st component.

1.My requirement is while click on display button.It will navigate to 2nd component and value should populate in the respective tab..But its not populating.........

we have to write the code in on action display button.Can u send what we have to write give some sample code..

In the onaction i am creating the instance and call component but its not working..............

Hi Venkat & Chengalarayulu D,

I am tried that but value is not populating in the tab.i am creating the instance and call component but its not working..............

Can u tell another way to achive this process...........

Hi Prabhu,

These values are static  or  dynamic(Depends on user action)......

If these values are static   then in com2  init() method  u have to generate ..... If it dynamic  you have to create interface node in comp2  u have to call that method in comp1 .

Hi Venkat,

My values is dynamic.I am created the interface node for the four component.But where i have to create the method.In comp1 or comp2.....

[Former Member · Accepted solution]

Prabhu,

u r calling comp2  in comp1  if yes then do below

create interface method in comp2  and call  the method in comp1(When ever u create instance of interface controller of comp2  at that u can call this interface method  and u can pass the parameters )

Hi Chengalarayulu,

My requirement is slight change to click the onaction we have to call another webdynpro component in a popup..

1st component-zr3_requests2->Contain the action button..

2nd component-zwd_tabstrip.

which component i have to create the window and what view i have to embedded in that window.....

[Former Member · Accepted solution]

Hi prabhu,

In 1st Component u have to create popup method ....   

-> create one window in comp1.. end embed  the view of comp2 into window...

then generate the code in action method  using codewizard  by mention the window name  in comp1...

regards,

venkat

[chengalarayulu · Accepted solution]

Prabhu,

Directly you can populate window of component-2 as popup,

if you feel it is difficult, just create a view in component-1, insert viewcontainer UI element, and create one more window, then embed the new view, then embed the window/view of component-2 into that, then test.

Hi Prabhu,

This your senario,on a technical stand point.Go for External window concept in WDP.

Hope this will be useful .
